What Does a PEO Actually Do?

A PEO is basically an outsourced HR department that partners with your business through something called co-employment. That means your employees are technically on the PEO’s books for tax and benefits purposes, but they still report to you and work for your business.

Here’s what PEOs typically handle:

• ✅ Payroll and tax filings

• ✅ Employee benefits and insurance

• ✅ Workers’ compensation and risk management

• ✅ HR compliance and legal guidance

• ✅ Onboarding, employee handbooks, and basic training

For small businesses, a PEO can unlock access to Fortune 500-level benefits and ease the stress of ever-changing labor laws (looking at you, California). 🌴

When Does a PEO Make Sense?

Not every business needs a PEO. But if any of these sound familiar, it might be time to consider one:

• ⏱️ You’re spending way too much time on payroll or HR questions

• 🏥 You want to offer better health insurance or 401(k) options

• 🌎 You’re expanding to multiple states and getting tripped up by compliance

• ⚠️ You’ve had a legal or tax scare and want to reduce risk

• 📈 You’re scaling quickly and need professional HR systems in place

If your business has between 5 and 200 employees, that’s the sweet spot where a PEO can really shine—delivering value, saving time, and helping you avoid costly mistakes.

How to Choose the Right PEO for You 🤔

Not all PEOs are created equal. Some cater to specific industries, others excel at benefits, and some are tech-driven platforms designed for busy founders.

Here’s what to look for when choosing a PEO:

🧠 HR Expertise

Do they have real experts on staff to help with tricky employee issues, terminations, or compliance questions?

🏗️ Industry Fit

Some PEOs specialize in healthcare, tech, construction, or hospitality. Look for one that understands your business model.

💸 Pricing Structure

PEOs usually charge a flat fee per employee or a percentage of total payroll. Ask for clarity on costs—and watch for hidden fees.

📍 Geographic Coverage

If you operate in multiple states, especially those with tricky labor laws, make sure your PEO has nationwide expertise.

💻 Tech Platform

Modern PEOs offer dashboards for payroll, time tracking, and benefits management. If ease of use matters, ask for a product demo.
